The weather was cold and sunny as fifteen volunteers completed this week's survey. Insects need warmth for their wings to work and many flies tolerate low winter temperatures better than bees, tending to outnumber them at nectar sources, as shown below. Exceptions are Honey Bees, which live in a toasty hive, and Bumble Bees, which vibrate their flight muscles to create heat.
